BNIB-E9x N54 Aux OEM Water Rad that fits in your driver side wheel well see pic.

This is also part of the Performance upgrade kit for the N54 that the BMW dealers are selling.

Fan not included (need part#2 or just the screen p/n51718044547) all the parts needed for install is included (hoses and brackets)- $375, I don't need this anymore because i traded my 2008 335i for the 2011 335is and it comes with it from factory.
